Area of Science:

  • Radiology
  • Otorhinolaryngology
  • Medical Imaging

Background:

  • Endoscopic sinus surgery requires precise visualization of sinonasal anatomy and disease extent.
  • Plain X-rays and magnetic resonance imaging (MRI) provide suboptimal information for surgical planning compared to CT.
  • Computerized tomography (CT) is considered the gold standard for pre-operative assessment.

Purpose of the Study:

  • To highlight the superiority of CT imaging in endoscopic sinus surgery planning.
  • To present optimized CT protocols for minimizing radiation exposure to the lens.
  • To outline key anatomical features critical for pre-operative evaluation.

Main Methods:

  • Review of CT imaging protocols used in endoscopic sinus surgery.
  • Analysis of image quality and radiation dose in different CT protocols.

  • Identification of critical anatomical landmarks for surgical safety.

    • Main Results:

    • CT provides superior detail of sinonasal anatomy and disease extent compared to X-ray and MRI.
    • Specific CT protocols effectively minimize radiation dose to the ocular lens.
    • Detailed anatomical evaluation pre-operatively enhances surgical safety and outcomes.

    Conclusions:

    • Computerized tomography is indispensable for safe and effective endoscopic sinus surgery.
    • Optimized CT protocols balance diagnostic image quality with radiation safety.
    • Thorough pre-operative anatomical assessment using CT is paramount for successful surgical intervention.
